FILING.

SPECIFICATION forming part of Letters Patent No. 763,526, dated June 28,1904.

Application filed October 21, 1903. Serial N0- l77,898 (No model.)

gineering for temporary and permanent purposes, such as cotter-dams,bases for permanent structures, permanent structures such as dams fordiverting, dividing, or arresting the flow of water, walls, and varioussub and su per terrene Works.

The general object of my invention is to provide an improved form ofinterlocking metallic piles with joints that offer a maximum ofresistance to separation or flexing with the use of a minimum amount ofmaterial and complexity of construction.

Another object is to provide the simplest possible form of pilingoffering the least possible amount of resistance when driven home, and astill further object is to provide a system of piles having joints whichinterlock positively, firmly, and closely against relative displacementand which offer rigid resistance against pressure on either side of thestructure by means of ribs extending from both sides thereof indifferent planes.

The invention consists in the foregoing and other'improvements embodiedin the novel details of construction hereinafter more fully described,illustrated in the drawings, and pointed out in the claims.

In the drawings, Figure 1 illustrates an end view, partly in section, ofa series of piles embodying my invention. Fig. 2 is an end or top viewshowing the arrangement for a corner. Fig. 3 is a perspective viewrepresenting a fragment of two piles joined. Fig. 4 represents anenlarged detail view of one section or substantially half of a pileembodying my invention.

Referring to the drawings, 2 represents one of the piles, (shown clearlyin its relation to adjacent piles in the sectioned portion of Fig. 1.)Said pile consists of substantially identical sections or channel-bars 33, each of which formed into channel, groove, or hook 5, adapt ed toengage the edge 6 of the opposite wing 7, which is straight, The twoplates have their body portions suitably apertured for rivets 8, and theopposite ends of said plates overlap each other, so that the bent orgrooved wings 4 extend from the opposite plates intermediate of theirends, while the straight wings 7 project in opposite directions from theends of. the body portion. herein referred to have reference to theextremities of the pile, as seen in Figs. 1, 2, and 4, or its Widthterminee, the extent of its length beingimmateria] for the purpose ofthis specification. Each pile, therefore, presents at and near each ofits ends a hookedanda straight wing, rib, or flangeprojecting inopposite directions and indifferent planes, so that the combinedresistance to lateral strain of each pair of wings is divided and eachwing supports the opposite plate intermediate of its ends, and provisionis made for portions 9, which overlap when a series of piles are joinedtogether, as shown in Fig. I. Said portions 9 are held upon each otherby the wings 7 engaging the bent portions 5, and as the latter engageboth sides and the edge of each Wing 7 the latter is held againstlateral movement with relation to the wing 4 of adjacent pile. Theseries. of piles are therefore firmly locked together against any but aslidingmovement upon each other, In order that water may pass throughthe joint thus formed, it must first pass in asubstantially 'semicircirlar path Within the channel formed by the hook or curved portion 5,thence in astraight line between the wings 4 and 7, when itmcets thewall interposed at right angles to its path by one of the portions 9 andits course is deflected between the portions 9 9 to be again interruptedby another wall at right angles to its path or the wing 4 and, finally,must pass around the edge of the opposite wing 7. It is evident,therefore, that in order to pass the joint the water is checked twice bywalls at right angles to its path and twice forced to completely reverseits direction of How. The

The ends v long path and the numerous obstructions interposed to adirect flow tend to readily gather and hold solids or sediment whichquickly seal the joint substantially water-tight. I accomplish all ofthese obstructions to flow of water through the joint with piles, eachconsisting of but two integral plates riveted together and overlappedand bent in the novel manner described. So far as I am awarev this hasnot been possible of accomplishment with constructions heretoforedevised, which have usually required separate reinforced parts rivetedor secured at the joints. These, while making the pile considerablythicker and stronger at the joint, have added nothing to the body of thepile or that portion intermediate of the joint portions.

By entirely obviating special reinforcements and making the pile as awhole out of two identical plates having similar wings, said wings andbody of the pile overlapping the entire width thereof, I am able to makea much cheaper, better, and stronger structure for all the purposes forwhich they are intended.' It will be observed also that I obviateriveting at the joints and that each of the members forming the latteris a rigid and integral part without reinforcements liable to work loosewhen hastily fastened together. Theonlyriveting I employ is that whichholds the two integral plates together, and upon these rivetspractically no bending strain is imposed on account of the hook portionsengaging opposite sides of the piles and opposite sides of oppositewings 7. 3

Another exceedingly valuable feature of my invention resides in theuniform thickness of the series of piles when joined together, the onlyadded thickness being the extreme end of the curved portion 5. hileIhaveshown the heads of the bolts or rivets 8 projecting beyond the surfacesof the plates, it is obvious that they may be countersunk therein,

in which event there would be no projections whatever to engage thewalls of the opening made in the earth as the pileis driven in. Thematerial being evenly or uniformly distributed there are no weak points.Itis obvious that joints formed by a double thickness of material addnothing to the rigidity of the structure between the joints, and, like achain, the whole thereof is no stronger than its weakest link, which inthis instance applies to bending strains rather than tensile strength.

The feature of uniform thickness or overlapping of the parts isexceptionally valuable in pile structures or dams which must withstand agreat deal of lateral pressure as well as the strain of impact whendriven into the earth.

In Fig. 2 is illustrated a method of forming the corner-piles forrectangular or angular structures, which consists of the angle 2',formed substantially of members 3 cut in two,

whereby is provided members 3 and 3, riveted together and overlapping,substantially as shown in Fig. 1, with the exception of variations intheir respective lengths and extent of projection over each other. Theupper side of the angle 2 has its member 3 projecting over the end ofthe member 3, and the lower side of the angle has its member 3projecting only sufliciently to cover the end of the member 3. The twosides of the angle thus formed are secured together, as shown, by meansof one row of rivets 8, only one rivet of which is shown in Fig. 2.

The method of joining the piles will be readily understood from theforegoing description. One of the piles being driven, the wing 6 of thenext pile is inserted in the groove or hook 5 of the first-mentionedpile, and the hook 5 of said next pile is caused to engage the wing 7 ofthe first pile and is then driven home, held in close engagement withthe pile already driven, and so on.

It is obvious that numerous modifications may be made in the embodimentof my invention without departing from the spirit thereof, and 1therefore do not desire to confine my invention to the specific detailsor form of construction herein shown and described.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A pile consisting of but two separatelyintegralmembers bolted or riveted together and having a straight and a hookedflange, said flanges being arranged substantially parallel but indifferent planes.

2. A pile consisting of a body portion having two pairs of flangesprojecting in opposite directions from said body portion, each flangeoccupying a separate plane, and means for interlocking said flanges.

3. A pile consisting of two substantially identical plates rivetedtogether, each of said plates having a pair of flanges projecting atanangle from its body and one of said flanges terminating in a hook.

4. A pile consisting of two substantially identical members rivetedtogether and having a pair of flanges at each end projecting in oppositedirections and in different planes, one of said flanges terminating in ahook and the other being substantially flat.

5. A pile consisting of a body portion having two flanges projecting inthe same direction from each side of said body and means forming anintegral portion of said flanges for interlocking same with a similaradjacent pile.

6. A pile consisting of two plates bent at their ends substantially atright angles, whereby is provided two flanges, one of said flangeshaving a hook portion and the other being plain, said plates partiallyoverlapping each other, and suitableriveting for securing said platestogether.

7. A pile consisting of two similar plates partially overlapping eachother, provided with two curved flanges extending in opposite directionsintermediate of its ends and two straight flanges extending in oppositedirections at its ends.

8. A pile consisting of a body portion having a pair ofoppositely-projecting hooks one near each end and anoppositely-projecting flange at each end adapted to engage a similarsaid hook of an adjacent pile.

9. A series of interlocking piles having substantially uniform thicknessthroughout, each pile provided with flanges projecting from both sidesthereof, the flanges on one side occupying different planes from theflanges on the other side, and means for interlocking the flanges ofadjacent piles.

10. A channel-bar for sheet-piling provided at one edge with a plainflange and at the opposite edge with a hooked flange corresponding ininterior outline to the exterior outline of the plain flange.

11. A channel-bar for sheet-piling provided with parallel flanges on thesame face of the channel, one of said flanges being a plain flange orlip and the other being a hooked flange corresponding in interioroutline to the exterior outline of the plain flange.

12. A section or unit for sheet-piling consisting of two channel-barssecured together face to face in parallel relation but offset laterallywith respect to each other, each channelbar provided with longitudinalparallel flanges on its opposite face from the other channel and one ofsaid flanges being a plain flange or lip while the other is ahookedflange corresponding in interior outline to the exterior outline of theplain flange, the two channels being secured together with the hookedflange of each channel inside of the plain flanged edge of the oppositechannel.

13. A section or unit for sheet-piling consisting of two channel-barssecured together face to face in parallel relation but oflset laterallywith respect to each other, each channel-bar being provided withlongitudinal parallel flanges on its opposite face from the otherchannel and one of said flanges being a plain flange or lip while theother is a hooked flange corresponding in interior outline to theexterior outline of the plain flange.
